Description
I will outline a general approach to quantum field theory in de Sitter and anti-de Sitter spaces, developed primarily at IHES in Bures-sur-Yvette over the past 30 years in collaboration with Jacques Bros and Henri Epstein, whose memory I wish to honour and to keep alive as long as I am able. I will also discuss my most recent results on a plane wave expansion of the anti de Sitter two-point Wightman function, along with some of its applications.
